(CNN) - Myanmar's Aung San Suu Kyi gave her Nobel speech in Norway on Saturday, more than two decades after she won the peace prize.

Her presence in Oslo, Norway, on a historic first trip to Europe after years of house arrest, signals the progress toward reform in Myanmar, also known as Burma, over the past year.

Suu Kyi was unable to accept the Nobel when it was awarded in 1991 because she was under house arrest in Myanmar. Her husband and two sons accepted it then on her behalf, paying tribute to her sacrifice.

Greeted by heartfelt applause from those gathered in Oslo City Hall, Suu Kyi spoke of what peace meant to her and also of her country's fragile progress toward democratic reform.

"Over the past year there have been signs that the endeavors of those who believe in democracy and human rights are beginning to bear fruit in Burma. There have been changes in a positive direction; steps towards democratization have been taken," she said.

"If I advocate cautious optimism it is not because I do not have faith in the future but because I do not want to encourage blind faith." FULL STORY
